Be it known that IYWALTER GORDON LAW- RENGE, asubject of the KingflofGreat Brit-' ain, and a resident of .214Worsley road, Winton,in thecounty of Lancasten'England, have invented certain newand useful.

Improvements in Windows; and I do hereby declare that the following is afull; clear; and exact description of the same.

The invention relates to improvements in windows, as described in thepresent specification and illustrated in the accompanying drawings thatform part of the same.

The invention consists essentially in the novelform of self adjustinghinge support for casement windows.

The objects of the invention are to be able to get at all parts of thewindow for cleaning purposes no matter which way the sash is swung, todevise a simple and efiicient means of supporting the sashes in casementwindows which will avoid all clogging and jamming of the sash at thehinged portion as the frame can readily be cleared of all obstruction,and generally to provide a simple, cheap and durable window.

In the drawings Figure 1 is a perspective view of the pivotal support orhinged member at the lower end of the sash showing the other hingemember attached to the frame. Fig. 2 is a plan view of the arrangementshown in Fig. 1 with a partly open'position of the sash indicated bydotted lines. Fig. 3

' is an enlarged sectional detail of a hinge pin 35 and slotted plate.Fig. 4 is a sectional view of another hinge pin and the slotted plate.

Like numerals of reference indicate cor responding parts in each figure.

Referring to the drawings 1 is a vertical rail of the window sash.

2 is a horizontal sash rail.

3 is a window frame formed of metal or wood as desired, though in theaccompanying drawings a metal frame is shown, also a metal sash.

4 is a hinge member rigidly secured to the horizontals of the frame 3and having a plate surface 5 parallel with the said horizontals and aparallel slot 6 extending the greater part of its length and a lug 7extending outwardly from one end of said plate portion 5 in an obliquedirection and formed in opposing curves 8 and 9 with a recessed interiorflanged at the sides by the flanges 10and 11, forming the under cuts 13.The under cuts 13 are formed by a cut into the longitudinal.undercorners of the lug .7, said lug having-in the, bed of the recessthe holes 14 withthe bevel edges 15.

16 s a bracket. formed with the boss. 17,

tending fromsaid boss into the slot 6, said plate extensions 18 beingrigidly secured to the vertical rail l andthe horizontal rail 2 at thecorner thereof. v

20 is a bracket flanged at itsinner end 21 and rigidly secured to thehorizontal rail 2 adjacent to a 'plate extension 18, said bracket 20extending'outwardly and carrying at the outer end thereof the pin casing22, said pin casing having a shoulder 23 in the interior thereof and atits lower end a flange 24 extending into the under cuts 13. I.

25 is a pin having at its lower end the round head 26 and extendingupwardly into and through said pin casing2 27 is a spiral springencircling the pin 25 between the flat inner side of the round head 26and the shoulder 23, thereby constantly exerting a downwardpressure onthe head 26 so that the said head will engage in one or other of theholes 14. The hinge members 4 and 20 are'seoured in pairs to the cornersof the window frame and to the sash as usual.
